The widow of American tourist Kurt Cochran says she feels "no hate" towards terrorist Khalid Masood after he killed the "love of my life" during the Westminster terror attack.

Melissa Cochran, who was also injured in the London attack, said she and her husband had been enjoying a "wonderful day" moments before Masood struck.

Melissa was joined by the Duke and Duchess of Cambridge and Prince Harry when she attended the Service of Hope memorial service for families and survivors at Westminster Abbey this week.

Melissa, who attended the service in a wheelchair, said the couple, from Utah, had been visiting London to celebrate their 25th wedding anniversary, when they went to cross the Westminster bridge on March 22.

Speaking to the BBC after the memorial service, Melissa broke down as she described her husband as "probably the best man I've ever met". "He was sweet and kind and I'm extremely proud of him and I'm very happy that the world now knows what a wonderful man he was," she added.

Melissa described the moment she found out her husband had been killed, saying she felt "crushed". "We just were having another wonderful day on our vacation and just enjoying the sights, taking pictures, making our way to the Abbey," she said.

She said she did not remember much after the couple went to cross the bridge and tragedy struck.

Kurt was one of five people killed and dozens injured during the London attack last month, including police officer Keith Palmer. Melissa herself suffered serious injuries including a broken leg, rib and gash to the head.

Yet despite her injuries and loss, she said she felt "no hate" after the horrific attack.

"I don't think I could heal my injuries or as a person if I had hate in my heart and Kurt wouldn't want that either so there is no hate," she said.

Melissa's comments mark a direct contrast to those made by the family of another victim, 75-year-old pensioner Leslie Rhodes, who said they wished Masood had lived so he could have "suffered the way that all the families now are suffering".
